This doesn't actually do a whole lot for existing code, because it's configured not to check the bodies of functions that don't have typed declarations. Meaningful checking can be introduced progressively from here; I started by configuring the pitch tracker modules to require type defs. Individual functions can also be checked, by adding types to their declarations.
Unfortunately pyqtProperty isn't type-checkable and does produce errors, so there's a fair amount of error-suppression noise for it :(
I noticed this in #201
